Comparative hematological analysis of Morada Nova and Santa Inês ewes in all reproductive stages

Abstract

RESUMO.-[Análise hematológica comparativa de ovelhas Morada Nova e Santa Inês em todos os estágios reprodutivos.] A análise hematológica fornece informação confiável sobre a saúde dos animais. É uma variável importante na avaliação da capacidade adaptativa e produtiva das raças sob condições ambientais desfavoráveis. É uma avaliação que aliada a outros fatores genéticos, ambientais e de manejo pode se tornar cada vez mais útil para a sustentabilidade futura da agricultura convencional em um ambiente quente. A capacidade adaptativa é afetada por alguns fatores como raça, gestação e lactação. It is an important variable in the assessment of adaptive and productive capacity of breeds under unfavorable environmental conditions. It is an assessment that combined with other genetic and environmental factors and management can become useful for the future sustainability of mainstream agriculture in a hot environment. Adaptive capacity is affected by some factors such as breed, pregnancy and lactation. Therefore, hematological profile is an important indicator of animal health and production. The objective of this study was to perform the comparative hematological analysis of Santa Inês and Morada Nova breeds (native ewes from Brazil) in all different reproductive stages. Twenty Santa Ines and 20 Morada Nova sheep distributed in a completely randomized design in a split-plot arrangement over time were used. To obtain blood counts, blood samples were collected by jugular venipuncture every 14 days, always in the morning, before the animals were released into the pasture. The Morada Nova breed had higher hemoglobin and total leukocyte count than Santa Inês breed. Regarding the influence of pregnancy and puerperium on the eritrogram, there was an increment in red blood cell, hemoglobin and packed cell volume of both breeds in middle pregnancy. However, had a reduction in late pregnancy. There were a reestablishment of the blood cell counts during the puerperium period. It was verified an increase on neutrophil: lymphocyte ratio indicated that ewes in the late pregnancy, postpartum and puerperium were under stress conditions compared to others reproductive stages. The total plasma proteins also increased during this period to compensate for the high nutritional requirements of the fetus, and these levels remained high until the end of the puerperal phase, when the lambs were weaned. The pregnancy and puerperium influenced all erythrocyte indices and changed the total leukocyte count. perfil hematológico é um indicador importante da saúde e produção animal. O objetivo deste estudo foi realizar a análise hematológica comparativa de ovelhas Morada Nova e Santa Inês (ovelhas nativas do Brasil) em todos os está-gios reprodutivos. Foram utilizadas 20 ovelhas Santa Inês e 20 Morada Nova distribuídas em um delineamento inteiramente casualizado, em parcelas subdivididas e medidas repetidas no tempo. Para a análise do sangue, foram coletadas amostras por venopunção jugular a cada 14 dias, sempre colhidas pela manhã, antes que os anim...

Pengaruh Bunting dan Laktasi Terhadap Hematologi dan Mineral Kambing Peranakan Ettawa di Kulonprogo, Yogyakarta, Indonesia

“…Rata-rata MCHC hasil penelitian ini tidak berbeda antara kambing bunting dengan kambing laktasi (p>0,05). Hasil ini sesuai dengan MCHC pada keledai bunting dan laktasi (Bonelli et al, 2016) serta kambing Egyptian Baladi bunting dan laktasi (Salem, 2017), kambing Baladi bunting dan laktasi (Azab & Abdel-Maksoud, 1999) dan sapi Nellore bunting dan laktasi (De Oliveira et al, 2019) serta domba Santa Inês bunting dan laktasi (Bezerra et al, 2017). Hasil ini menunjukkan tidak adanya penurunan kapasitas total oksigen yang beredar dalam sirkulasi antara kambing bunting dan laktasi tersebut (Poljičak-Milas et al, 2009) karena ratarata MCHC lebih menggambarkan indeks eritrosit (Mohammad, 2011).…”

“…Keseluruhan rata-rata leukosit hasil penelitian ini masuk dalam referensi normal sebesar 4,00-13,00 ribu/µL (Byers &Kramer, 2010), juga sesuai dengan leukosit pada kambing Omani sebesar 14,6±3,32 ribu/µL, kambing Barbari sebesar 12,88±4,83 ribu/µL, kambing Black Aardi sebesar 12,20±2,97 ribu/µL, dan kambing Damascus sebesar 8,05±2,06 ribu/µL (Al-Bulushi et al, 2017). Rata-rata leukosit tidak berbeda antara kambing bunting dan laktasi (p>0,05), sesuai dengan leukosit pada kambing bunting dan laktasi Nguni, Boer dan Non-descript di Afrika Selatan (Idamokoro et al, 2018), domba Santa Inês bunting dan laktasi serta domba Morada Nova pada akhir kebuntingan dan postpartum (Bezerra et al, 2017), sapi bunting pada trisemester dan seminggu awal laktasi di Zaria (Ate, 2006), serta sapi Nellore bunting dan laktasi (De Oliveira et al, 2019). Hasil ini menunjukkan bahwa antara kambing bunting dan laktasi tidak ditemukan indikasi keradangan, ataupun respon stres yang memicu hormon kelenjar adrenal dalam sistem sirkulasi dalam menstimulasi peningkatan leukosit.…”

Hematological Profile of Aceh Cattle

“…Studies conducted on Aceh cattle, including physiological baseline studies, are relatively fewer compared to other Indonesian local cattle breed. The knowledge of physiological status is essential as a reference for the implementation of various The hematological profile is one of the physiological variables that can be used to determine health status, production, and animal welfare of livestock (Siswanto, 2011;Otter, 2013;Roland et al, 2014;Bezerra et al, 2017;Brunel et al, 2018). A proper blood profile can support the physiological processes of the livestock so they can provide optimal performance (Ali et al, 2013).…”

“…A proper blood profile can support the physiological processes of the livestock so they can provide optimal performance (Ali et al, 2013). Also, ideal physiological profiles can have an impact on increasing livestock production and productivity (Bezerra et al, 2017). The parameter of hematology profile of livestock that commonly examined are erythrocytes, leukocytes, hemoglobin, hematocrit, erythrocyte index, and platelets.…”

Consumo de follaje de Erythrina americana Miller en ovejas Blackbelly x Pelibuey

“…Mientras que las medias de cuadrados mínimos ± EE para hemoglobina (g dl -1 ) y hematocrito en los días 1, 14 y 28 fueron: 11.2 a ± 0.5, 10.1 b ± 0.5 y 9.4 b ± 0.5, respectivamente y, 22.5 b ± 1.3, 26.6 a ± 1.3 y 26.9 a ± 1.3, respectivamente. Los valores en las variables hemáticas estudiadas se encuentran dentro de los límites indicados para ovinos de pelo en pastoreo en la región tropical (49) . Los niveles de consumo de follaje de E. americana que tuvieron las ovejas durante las cuatro semanas del estudio permitieron que las variables hematológicas estudiadas se mantuvieran dentro de los límites indicados para ovejas que no se encuentran en fase de gestación y lactación.…”
